s FLUSHING DEV-ICE.

Application filed June 30, 1920. Serial No. 393,092.

ToaZZ @0110? it may concern Be it known that I, THOMAS R. BEGGS, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Flushing Device, of which the following is a specification.

This invention refers to a flushing device and its object is to provide a structure by means of which a flow of water directly from a service pipe may be delivered to a toilet bowl without causing hammering and also avoiding the use of a flush tank.

This application is a continuation of my application Serial No. 297 18 for a flushometer, filed May 14:, 1919, in so far as the two applications contain common subject matter. In accordance with the invention there is provided a structure of small size which, after being started, will automatically maintain the full initial flow of water for the full time for which the device is set, and the flushing valve will then close rapidly but will be checked just before becoming seated in order to permit the bowl to refill.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing in the drawings but may be changed and modified so long as 'such'changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims. 1

sideredas constituting a part of the service system ofthe house or other building in which the flushing device is installed. The top of the body member 1 is formed with an outstanding flange 1. The flange enters a socket or flange portion 5 of an upper or covermember 6 to which the body member is secured by means of screws 7 or in any other appropriate manner, and a diaphragm 8 of leather or other suitable material, forms a division wall between the upper and lower members of the casing. The diaphragm 8 forms the top wall of the chamber 2 and the bottom wall of another chamber 9 which latter is defined within the cover member (3. Uprising from the cover member 6 is a neck 10 with stepped walls 11 12 13 surmounted by a circumferential gl'OOVO 142., with the walls 11, 12 and 13 and groove 14: gradually increasing in diameter and finally terminating in a ledge 15 above which there is a tubular continuation 16 rising to an appropriate height and provided at the upper end with a screw cap 17 by which the tubular continuation or cylinder 16 is closed at the upper end in a waterand air tight manner.

In the neck 10 there is located a hollow plug 18 formed exteriorly with stepped flanges '19, 20, 21 and 22 between each of which and a corresponding ledge 11. 12. 13 and 15 is a packing ring 23, so that the plug is encircled. by a series of annular channels 2 1, 25 and 26. The plug 18 is provided with a longitudinal central port or passage .37 with which the several channels 2 1;. 25' and 26 communicate through series of ports The plug 18 is held in place in the neck 10 by means of the flanges 19 to 22 resting on the shoulders or ledges'll, 12. 13 and 15 and r by a nut 29 screwed on to the smaller end of the plug which has a threaded extension 3 for the purpose.

The port or passage 2'? is of even diameter throughout to house a piston or slide valve 31 provided with packing rings 32, 33 and 3 in a'suitably spaced position so as to open and close the ports 28 as the slide valveor piston 31 is moved lengthwise of r the port 27. l/Vithin the slide valve 31 is an axial passage 35 Opening through the upper. end of the slide valve, where the latter is threaded, for the reception'of a clamp nut 36 so arranged as to hold the packing rings 33 and 34 in place on the piston. Between the rings 33 and 34 is a spacer 37 with a port 38 therein and so arranged that when i moved lengthwise of the cylinder 16 without leakage of water past it, due to the presence:

of the packing 40.

The slide valve 31 has a screw-threaded extension 42* entering its lower end and having a clamp nut 42 serving tohold the packing ring 32 thereto, and the slide valve is continued below the nut 42 and carries a ball 43 seated in a block 44, constituting a ball and socket joint of some flexibility, the block 44 being provided with an axially extended threaded stem 45. The block 44 engages the upper face of the diaphragm 8 and on the opposite or under face of the diaphragm there is a clamp plate 46, a gasket 47 and an internally threaded block 48 serving as a clamp nut to force the parts together, thus binding the block 44 and the diaphragm 8 together. The stem extends through and is guided by a spider 49 lorated in a pipe extension 50 of the body member 1, said extension 50 having terminal screw threads 51 by means of which the pipe 50 may be connected to a toilet bow]. The pipe extension 50 is entered by the block 48, which is concentric with the pipe 50 so that the outlet leading to the toilet bowl is constricted.

' The end of the pipe 50 within the chamber 2 terminates in a valve seat53 with which the gasket 47 engages when down thus clos- 7 ing communication between the chamber'Z and the pipe 50. In this position of the parts, shown in Fig. 3, the slide valve 31 closes the lower end of the bore 27 except for ports 54 through the walls of the plug 18 below the nut 29. The bore 27 communicates through a set of ports 28 with the same upper casing member 6 is provided with aunt-her offset 57 having an outlet the free passage of water past it.

bracket 72 1s providedwith a finger 74-5-13 chamber 58 therein with which there com- -municates a duct59 coming from the channel 25. V r r V The offset 57 carries a plunger guide 60 in which there is mounted a plungerfil having a rising tendency imparted to it by a spring 62. The plunger 61 is continued as a stem 61 through the housing 60 into the cham' ber 9 where the plunger stem carries a laterally expanded head 63 in the path of which is another laterallyexpanded head '64 on the lower end of a rod 65 rising into a guide passage 66 formed in an ofiset 67 on one side of the neck 10 and cylinder 16, the ofiset 67 being conveniently formed by casting it in place. The stem 61 carries a cup leather 61 engaging'the plunger head 61 and there by preventing leakage.

The plunger guide 60, where it passes i through the chamber 58, has holes or ports 58*, and the plunger 61 has longitudinal ribs 6O providing passageways for, the. water,

between the plunger guide'60 and the plun-= ger stem 61% so that when the plunger is depressed, the chambers 58' and 9 are in com munication with each other "through the ports 58 and the spaces between the ribs 60?. The plunger stem 61 holds a washer 63 against'the head63 to serve as; a valve for. V r

The rod 65 isof sufiicien-t length to reach the lower end of the plunger guide 60.

nearly to the top of tliecylinder 16 through the passage 66a'nd near the bottom of said passage carriesapiston or slidable valve 68 capable of moving between differently placed ports 69 and 70. 'A port 71 affords communication between passage 66 and the annular channel 24. At the upper end of the rod 65 there is secured a bracket 72 which may be conveniently clamped into place by a notched lock nut 73 peri itting 'l he tending into the interior. of the cylinder 16 and there carrying a set screw75to act as an adjustable abutment;for the piston or plunger 39. Carried by the rod 165 is an elastic friction member? 6 a-rranged 'to hold the rod 65 in adjustedpositions but yielding to the engagement of the heads63 with the head'64 upon the depression of the plunger 61. i

Atone side of the cylinder 16 ther-e ils formed an offset boss 77 constituting.afsupport for a hub 78 'of amanipulating handle 79-, the hub fitting snugly and freely on the boss and being there'jheld by a. suitable set screw 80, passing through a spacer sleeve 80* which prevents binding of the "hub 7 8 when the screw'is firmly seated. In 'order to restrict the movement of the handle 79 the hub 78 is provided with a" concealed groove 81 into which projects a stop screw 82 in the path of a pin or screw 83 carried by the hub Within the groove .81. 7 The hub 78 has a finger 84 projecting therefrom in position to engage the plunger 61 so that on manipulation of the lever or handle 79 the plunger 61 is actuated in a direction against the spring 62 so as to cause the head 63 to engage and depress the head 64 and this correspondingly depresses the rod 65 and opens the passage 71, closes the port 69 and opens the port 70.

The chamber 58 in the boss 57 is connected by a duct 85, constituting an exhaust duct, with another duct 86in the base of the upper section 6 of the casing. The duct 86 communicates through a passage 87 through the diaphragm 8 where it is clamped between the two casing members 1 and 6 with another conduit 88 leading into the pipe and so discharging into the flush bowl.

With the parts in the position shown in Fig. 3 the flushing device, with the exception of the pipe 50, is full of water and water at service pressure occupies thechamher 2. The water at service pressure also flows by way of the duct Fig. 5 to the channel 14 and thence by another duct 89 in the neck 10 to a space or channel 90 Figs. 3 and 5 surrounding the nut 29 and the Water finds its way into the chamber 9 by way of the port 69. The result is that the chambers 2 and 9 contain water at service pressure and the differential pressure on the opposite sides of the diaphragm, holds the valve 46 firmly on its seat. The slide valve 31 is consequently held in its lowermost position, as seen in Fig. 3, and the service pressure also is transmitted from chamber 9 through ports 54, and the lowermost ports 28 into channel 24, and thence through port 71 and passage 66, to the cylinder 16 above the plunger 39. At this time, the lower part of the cylinder 16 below the plunger 39, is in communication through the bore 35, port 38, channel 25 and passage'59, with the chamber 58, which is always connected through ducts 85, 86, 87 and 88, with the outlet pipe 50.

When the handle 79 is manipulated to de:- press the plunger 61, and to simultaneously lower the rod 65 and valve 68, the latter closes the port 69, thus relieving the pressure in chamber 9 as well as in the upper part of chamber 16, which has thus far been in communication with chamber 9. The diaphragm 8 is therefore immediately raised by the pressure in chamber 2, while the chamber 9 is initially vented through the passages between the ribs and through the ports 58' and chamber 58. As the diaphragm rises, it carries the slide valve 31 upwardly until the packing ring 32 is above the ports 54 and the packing 33 is above thei'ntermediate ports 28 leading into the channel 25 which is connected through the port 59 with the exhaust chamber At the same tim acisn rin 34,

has uncovered the uppermost port 28 leading from the channel 26 so that pressure enters through passage channel 26, port 38 and bore 35 underneath the plunger 39.

The plunger 61, as soon as the handle 7 9 is released. is returned to normal position by the spring 62, but the rod andvalve 68 remain depressed until restored by the operation of the plunger 39 as hereinafter explained. The chamber 9, however. continues to be vented through ports and 71. channel 24, the lower two sets of ports 28, the channel 25, port 59 and exhaust chamber 58.

This condition prevails until the service water slowly entering through the bore 35 raises the plunger 39, until the latter striking the screw raises the valve 68 again to the position shown in full lines in Fig. 4. Meanwhile the valve 45 is wide open and the bowl is being flushed. By adjusting the screw 75, the length of the travel of the plunger may be varied to thereby vary the duration of the flushing operation.

As soon as the valve 68 is raised, the uncovering of port 69 again restores pressure to the chamber 9. This again lowers the diaphragm 8, valve 46 and slide valve 31, until the ports 54 are uncovered. At the. same time the lower part of chamber 16 beneath the plunger 39 is again vented through the bore 35, port 38. channel 25, port 59 and exhaust chamber 58. ,As soon as the ports 54 are uncovered, the pressure on the upper surface of the diaphragm'8 is relieved and the water, as fast as it enters the chamber 9 through port 69, passes outtherefrom through ports 54. the lowermost ports 28, channel 24, port 71 and passage 66, into the chamber 16 above the plunger 39. This relief of the pressure on the upper surface of the diaphragm 8, permits the valve 46 to stop in its descent just before it becomes seated and permits sealing water to trickle underneath the same into the bowl to re-fill it while the plunger 39 is descending.

7 When the plunger 39 reaches its lowermost position, there is no longer any escape for the water entering the chamber 9. and

full service pressure is again restored therein and the valve then immediately becomes quietly and firmly seated and all of theparts remain at rest until the handle 79 is again depressed The hall and socket joint 43 and the threaded stem 42 thereof permit adjustments to vary the time of admission of sealing water to the bowl. By this construction, means are provided to adjust the rate of refill of the bowl. l

The opening and closing of the flushing device is due solely to the action of hydraulic pressure resulting in the establishment of differences of pressure on opposite sides of the diaphragm by which back pressure is 'obtained to an eXtent causing the various operations to take place. 7

The flushing device may be readily adjusted to deliver a determined quantity of water at each flushing and consequentlyis susceptible of use for measuring purposes. While the device dividing chambers 2 and v9 from each other is shown as in the .form

of a flexible diaphragm it is to be understood that it may be in other forms as, for instance,'it may comprise a yieldable member in the form of a piston movable in the body member and serving to divide chamber 2 from chamber 9. I

It is to be observed that Figs. and 4 .show but'one port 28 in the channel 26 while the other channels 24 and 25 are provided with several such ports. This pro- .vides for a throttling of the flow through the channel 26 so that the plunger 39 is -raised slowly but may fall with comparative i that chamber in the body member remote rapidity, because of the larger combined area of the ports 28 in the respective channels 24 and 25. This showing is to be taken as merely indicative, because more than one port 28 may be used, or other arrangement may be employed, so long as the capacity thereof is sufliciently small.
